Outline of Final Research Achievements

RNA splicing, which removes intron, interventing sequence in the gene, is essential to produce functional molecule from the genes. Some genes for transfer RNAs (tRNAs), which carry amino acid to ribosome, protein synthesis machinery, have intron(s). Eukaryotic tRNA splicing enzymes have been analyzed from a very few organisms, and the entire characterization is remained to be solved. I analyzed RNA splicing enzymes in parasitic kinetoplastid protozoa. As a results, I elucidated that an RNA ligase in kinetoplastid protozoa had been acquired from an bacterial lineage via lateral horizontal gene transfer.
